 * state save/load (quick & VMU).
 * compress data saving. 
 * auto frameskip.
 * VMU menu (you can remove VMU files on NesterDC).
 * VMU saving works on long filename.


----------------------------------------
** NOTE **
 VMU blocks use 

  most case: 
   - normal saving(nes): 3-9 blocks 
   - normal saving(fds): 3 blocks 
   - state saving(nes):  6-20 blocks 
   - state saving(fds):  66 blocks 

  worst case: (calculated by assuming compression had no effect)
   - normal saving(nes): 18 blocks (40 blocks if MMC5)
   - normal saving(fds): 520 blocks
   - state saving(nes):  96 blocks (240 blocks if MMC5)
   - state saving(fds):  700 blocks


----------------------------------------
** STATE SAVE NOTE **

About quick state save: 
 quick-state-save shares savefile with all ROMs. 

 It's cleared when exit game 
(more exactly, it's cleared when load next ROM. 
so, remaining the quick state save data, even though you quit game, 
if you select the same ROM again.)


About VMU state save: 
 VMU-state-save makes a file per ROM. 

 It's saved to VMU, so you can load state after quit NesterDC. 


----------------------------------------
** NOTE **
 VMU LCD info

 * in main menu

 +--------------+ 
 | VMU FREE:    |  <- free blocks in VMU. 
 |  81 BLOCKS   |
 |              |
 | NESTERDC     |  <- NesterDC version. 
 |  6.0 RELEASE |
 +--------------+


 * during game

 +--------------+
 | FRAME RATE:  |  <- frame skip rate. 
 |  AUTO: x1.0  |
 | AUTOFIRE: N  |  <- autofire-mode status. 
 |              |
 | METROID.FDS  |  <- ROM file name. 
 +--------------+


========================================
NesterDC filesystem hierarchy is

--------------------
    1st track (audio)
     audio.raw (or your favorite caution.wav)

    2nd track (data)
     /1ST_READ.BIN
     /pics/credits.bmp
     /pics/menu.bmp
     /pics/...
     /games/game.nes
     /games/disksys.rom
     /games/super_mario.nes
     /games/favorite/castlevania1.nes
     /games/favorite/castlevania2.nes
     /games/favorite/castlevania3.nes
     /games/fds/metroid.fds
     /games/fds/zelda.fds
     /games/...
     /genie/super_mario_3/high_jump
     /genie/super_mario_3/high_speed
     /genie/...


--------------------
** NOTE ** 
  - If you play FDS games, need /games/disksys.rom.
  - If you use Rock Ridge format, there is no limit for filename. 
  - Max ROM files is 1024 per one directory. 


========================================
How to compile

1. edit nesterdc-6.0/dcmake
2. dcmake in top dir


--------------------
** NOTE **

My develop environment

 * NesterDC developing 
  - binutils-2.11.2
  - gcc-3.0.3
  - FreeBSD 4-stable

 * buring CD
  - NetBSD current
  - mkisofs + cdrecord

--------------------
** CAUTION **

I have no Windows PC, and I don't know HOWTO write CDs 
using Windows specific tools (DiskJuggler, Nero, ...).
